“N” indicates the (N)ormal, single interrupt per port mode. The “S” indicates the (S)hared
interrupt mode, which allows more than one port to access a single IRQ. The (M) indicates the
inclusion of a 1K OHM pull-down resistor required on one port when sharing interrupts.

Set the jumpers to "N" for single interrupt mode. This setting is the normal setting for most appli-
cations.

Set the jumpers to "S" for shared interrupt mode on all blocks sharing an IRQ except one. Set
that port block for "M". This provides the pull-down resistor circuit that makes sharing of IRQ's
possible. If you are using morethan one WINCOMM4 or a compatible card in a BUS, you
